I am most worried from about weeks 22-30ish.

A bad thing before this time basically means no chance of survival which is wrenching.

A bad thing after this time means probably survival with a chance of some lingering effects.

But during this window of time, not an exact science of course, a bad thing would probably mean at least a number of weeks in the NICU. And other possible bad long term outcomes.

Does anyone else worry about this period the most?
